I have a patch whose hg commit message is:
Bug 742165. isArrayBuffer should be true for |ArrayBuffer?| arguments. r=khuey
When I uploaded it using vanilla "hg bzexport -r :khuey", I ended up with an attachment with this description "isArrayBuffer should be true for |ArrayBuffe arguments."
Note that the "?|" part went away.

Created attachment 614908[details][diff][review]
reviewer parsing is too loose
Require a leading alphanumeric, at least. I probably ought to figure out what the valid set of characters is for the reviewer.
